ruby - 合并来自两个单独数组的字符串元素

我有两个阵列

names = ["name1", "name2"]
tracks = ["track1", "track2"]

我想把这两个数组合并成一个新数组

data => ["name1 track1", "name2 track2"]

我试了一下

1)   @data = @name.zip(@tracks)flatten
     produces ["name1", "track1", "name2", "track2"]

2)   @data = @name.at(0).concat(@tracks.at(0)) + @name.at(1).concat(@tracks.at(1))
     produces ["name1track1name2track2"]

3)   @name.each do |n|
      @tracks.each do |t|
       @data.push n + " " + t
       end
     end
     produces ["name1 track1", "name1 track2", "name2 track1", "name2 track2"]

我似乎解决不了这个问题我很感激你的帮助。

最佳答案

names  = ["name1", "name2"] #note the "="
tracks = ["track1", "track2"]

p names.zip(tracks).map{|e| e.join(" ")}
#=> ["name1 track1", "name2 track2"]
